J. deVos, Wenham, Mass., assignors to General Electric Company, a corporation of New York Filed Mar. 22, 1965, Ser. No. 441,646 18 Claims. (Cl. 240-3) ABSTRACT OF THE DISCLOSURE Floodlight comprises a housing enclosing a reflector and lamp sockets and covered at its front opening with a framed window pane secured to the frame with pushin clips and held spaced from the frame to provide a drainage opening therebetween, the frame being hingedly secured to the housing by a wire hinge permitting the frame to be moved entirely away from the housing opening and having means for securing the frame to the housing while limiting the compression on a gasket mounted on the reflector between the frame and housing.

The present invention relates to floodlights, and more particularly to a compact weatherproof floodlight adapted for use in various outdoor lighting applications.

Prior types of floodlights, such as those used for illuminating building facades, signs, sports areas, and the like, have had certain drawbacks in terms of manufacturing procedures and economics, maintenance difliculties, and other respects. For example, in prior floodlight constructions, the door frame attachment to the floodlight housing was often such that it did not permit unhindered access to the interior of the device for maintenance operations, such as re-lamping. In other cases,

the mounting and sealing arrangements for the cover window were diflicult to manufacture and assemble and did not provide adequately for drainage of water off the unit or prevent leakage through the window seal of accumulated water. In known types of floodlights, the lamp sockets were commonly inserted through openings in the housing walls, through which water would have access into the unit and lead to operating problems.

It is an object of the invention to provide an improved floodlight construction which avoids these and other disadvantages of the prior types of floodlights.

It is another object of the invention to provide a compact, weatherproof, economically manufactured floodlight device which is capable of rapid installation and simple maintenance, and is adapted for a wide variety of outdoor lighting applications and conditions.

Specific objects of the invention include the provision of an improved closure arrangement for the floodlight to enable unimpeded access to the light source and reflector of the floodlight for facilitating lamp removal and replacement or other servicing, of an improved window mounting construction to permit exterior drainage of water therefrom while effectively sealing the interior of the floodlight, and of a floodlight housing having improved cooling and sealing features.

Other objects and advantages will become apparent from the following description and the appended claims.

With the above objects in view, the present invention in one of its aspects relates to a floodlight which comprises a housing having walls defining an interior chamber and a front window opening, lamp socket means mounted on the walls of the housing in the chamber, a concave reflector fitting within the interior housing chamber and having at least one opening adjacent the lamp socket means, cover means including a transparent, lenticular or translucent window pane closing the front window opening of the housing, and hinge means swingably conecting the cover means to the housing for movement of the cover means entirely away from the front window opening to a position spaced a substantial distance therefrom to provide unimpeded access to the interior housing chamber.

The invention will be better understood from the following description taken in conjunction with the accompanying drawings, in which:

FIGURE 10 is a perspective view of the floodlight with a shield attached; and

FIGURE 11 is an enlarged fragmentary view in section of the FIGURE 10 assembly taken along the line 1111.

Referring now to the drawings, and particularly to FIGURE 1, there is shown a floodlight construction in accordance with the invention and comprising a housing 1 of generally rectangular shape and made, for example, of cast aluminum and having an open front closed by a cover unit 2 comprising frame 3 having mounted therein transparent, lenticular or translucent window pane 4 made of tempered, heat and shock resistant glass, or the like. The rear of housing 1 is formed with a number of integral fins 5 (see FIGURE 2) for radiating and dissipating heat generated in the housing during operation of the floodlight. At opposite ends of housing 1 the walls of the housing are formed on their inner surfaces with bosses 6 defining therebetween a recess 7 in which is received a lamp socket 8 formed of suitable electrical insulating material such as porcelain or steatite and having embedded therein a suitable electrically conducting lamp contact member. Also received in recess 7 is coil spring 9 which urges socket 8 into yieldable engagement with shoulder portions of bosses 6 as shown and with projecting ears 8a of the socket extending beyond bosses 6. Plate 10 (see FIGURE 1a) secured by screws or the like to bosses 6 covers recess 7 and retains socket 8 and spring 9 therein.

Concave reflector 11 fitting within housing 1 is formed with a flanged rim 11a (see FIGURES 4 and 5) having a gasket 12 thereon which seats on the rim of housing 1 when reflector I1 is in operative position, the reflector being secured to housing 1 by a plurality of screws 13 or the like. Reflector 11 is bent inwardly at its opposite end walls, as shown in FIG. 1a, and has openings 11]) at opposite ends adjacent sockets 8, the sockets being spaced rearwardly of the openings. Access is thus provided for operative yieldable engagement of the contact ends of an elongated lamp L with sockets 8, while the lamp ends are protected from excessive heating which might occur if they were located on the front side of reflector 11.

As seen in FIGURE 1a, which shows details of the lamp socket and contact arrangement and wherein the front projecting ear 8a is partly broken away for clarity, the contact end of lamp L extends between ears 8a and engages the socket contact which projects into the space between ears 8a.

As seen in FIGURES 4 and 5, housing 1 is formed with a continuous groove 14 extending around its rim in which gasket 12 is received and seated when reflector 11 is placed in position. Gasket 12 is preferably made of a heat resistant resilient material such as siicone rubber and preferably has a hollow portion as shown in FIGURE 5. When reflector 11 is screwed into assembly with the rim of housing 1, gasket 12 is compressed and forms a liquid tight seal between the perimeter of reflector 11 and housing 1. When compressed, gasket 12 tends to acquire a shape such as shown in FIGURES and 9 wherein its exposed sealing surface has lateral edge portions higher than the depressed central portion, and the gasket thus provides in effect a double seal.

Cover unit 2, comprising frame 3 and window pane 4, is swingably attached to housing 1 by means which enable complete displacement of cover unit 2 away from the housing opening for free and unhindered accessibility to the interior for replacing the lamp and which also provide for ready and accurate positioning of the cover unit 2 over the housing opening for closing the latter.

For this purpose, cover unit 2 is swingably attached to housing 1 along the upper edge thereof by a detachable wire bail or hinge member 20 of generally U-shape having a main portion 20a and arms 20b, 20c. Housing 1 is formed along its upper edge with a channel member 21 having an elongated groove 21a open toward the front of the housing and in which main portion 20a of wire hinge 20 is seated. Housing 1 is further formed with hearing bosses 22 and 23 (see FIG. 2) spaced respectively from opposite ends of channel member 21 and having rearwardly facing grooves therein in which wire hinge 20 is also received. The grooves in member 21 and bosses 22, 23 are sufiiciently wide to permit wire hinge 20 to freely rotate therein. As seen in FIGURE 6 showing the details of construction of bearing bosses 22, 23, a U- shaped wire retaining member 24 is arranged embracing boss 23 and having looped arm portions 24a, b engaging wire hinge member 20 for holding the latter within the groove on the rear side of the boss. Wire hinge 20 is so proportioned that main portion 20a extends nearly to the opposite ends of housing 1, and arm portions 20b, 20c

each have a length approximately half the vertical dimension of the front face of housing 1, as viewed in FIGURE 1. The free ends of arm portions 20b, 200 are bent outwardly and are inserted in apertures formed in embossed portions 3a, 3b in the sides of cover frame 3 for connecting cover unit 2 to housing 1. The arrangement is such that cover unit 2 is pivotally secured to the bent ends of arms 20b, 0 which are yieldably retained in position in the frame apertures by the inherent resiliency of arms 20b, 0, which in normal (i.e., unstressed) condition diverge somewhat from each other. Hinge arms 20b, 0 may be readily disengaged from frame 3 simply by pushing them inwardly toward each other. By virtue of the described construction, cover unit 2 may be lifted (as seen in FIG- URE 4) and swung completely away from the opening in housing 1 and laid on top of housing 1, thereby providing free access to its interior. The hinge arrangement also provides for simultaneous contact and uniform compression of window pane 4 with all parts of sealing gasket 12 on reflector 11 as cover unit 2 is moved into closed position over housing 1, thus obtaining better sealing conditions and prolonging the useful life of the gasket.

Frame 3 of cover unit 2 is flange 3c which surrounds and substantially covers the described hinging and gasket structures adjacent the housing opening when the cover unit 2 is secured in closed posihingedly formed with a peripheral tion over housing 1, as seen in the side view of FIGURE 3. The means for securing frame 3 to the housing in closed position comprise internally threaded hollow bosses 35 in the corners of flange 1a of housing 1 (see FIGURES 5 and 9) and screws 36 arranged in tubular bosses 37' projecting from the rear surface of frame 3 for engagement with threaded bosses 35. As seen in FIGURE 5, the head of screw 36 rests on an annular ledge 37a constricting the passage in boss 37, so as to draw frame 3 into closed position over housing 1 when the screws 36 are tightened. As seen in FIGURE 9, when frame 3 is in fully closed position, window pane 4 compresses gasket 12 in sealing relation, but the extent of compression is limited by the engagement of tubular boss 37 of frame 3 with hollow boss 35 of housing 1. Bosses 35 and 37 thus serve as combined stop and fastening means.

The recessed position of .the head of screw 36 within tubular boss 37 lessens the risk of ready tampering with the fastening of the fioodlight cover unit without the aid of a screwdriver, while at the same time the recess serves as a guide for inserting a screwdriver to unfasten the door when necessary. Advantageously, screws 36 are made captive within the frame bosses 37 to prevent their loss when disengaged from the housing for removing the cover unit. Thismay be accomplished, for example, by providing enlarged threaded end portions of the screws as shown in FIGURE 5, wherein. the diameter of the threads at the crown is greater than the diameter of the aperture in ledge 370, while the diameter at the base of the threads is smaller than the latter aperture to permit the screws to be removed by rotation in the aperture.

Referring now to FIGURE 7 showing the inner (or rear) side of cover unit 2, the mounting of window pane 4 on frame 3 is achieved by means of generally U-shaped spring wire clips 30 removably secured to frame 3 at its four corners. As seen in the detailed view of FIGURE8, each spring clip 30 is bent at an angle and has two looped end portions fitting snugly in a pair of adjacent holes formed in boss 31 in frame 3, and'has a main bight portion 30a bearing resiliently against the inner side of window pane 4 for holding the latter in engagement with resilient bearing pads or bumpers 32 suitably secured to a supporting boss 33 on frame 3. A plurality of such resilient bumpers 32 are provided spaced around frame 3 for holding window pane 4 spaced from the inner frame surface.

When cover unit 2 is placed in closed position over housing 1 and screws 36 tightened in housing bosses 35,

window pane 4 compresses gasket 12, as shown in FIG URE 9, to provide a fluid tight double seal for the interior of the housing. At the same time, window pane 4 is spaced from frame 3 around most of its margin, and there is provided thereby means for readily draining any water which may fall on the surface of the window pane, and thus assisting in maintaining the cover glass 4 clean when the latter is arranged facing substantially upwardly.

Where desired, a shield or visor 40, as shown in FIG- URE 10, may be readily attached to the floodlight unit. For this purpose, the inner edge of door frame 3 which defines the window opening is advantageously formed with a rearward lip 3d whereby shield 40, which has a complementary lip portion 40a, may engage frame 3. Shield 40 may be attached to the floodlight simply by loosening the four front retaining screws 36 and pushing window pane 4 inwardly somewhat so that lip 40:: of the shield can be inserted in the space between window pane 4 and frame 3 and snapped into engagement with lip 3d of frame 3. The shield is then secured firmly in place by tightening screws 36. Similarly an end shield or a boxlike shield utilizing two pieces as described above might be likewise formed and installed, as desired.

The rear side of housing 1 is formed with an integral supporting boss 41 (see FIGURES 2 and 4) to which is secured a swivel support 42 comprising separable interengaging toother members 43 and 44. Swivel member 44 is integrally formed with a connecting bar 45, the latter having projecting contact members 45a, b, c and d spaced therearound which engage housing boss 41. Retaining bolts 46 are screwed into boss 41 to secure connecting member 45 to the housing. Connecting support member 45 thus has only limited contact with housing 1, and this arrangement coupled with the provision of a space between member 45 and housing boss 41 for passage of cooling air, results in substantial reduction in heat flow between the housing and its exterior support and produces more than 100 C. lower temperature in the exterior support as compared to that in the housing.

Swivel member 43, which is separably connected to swivel member 44 by bolt 47 passing through the axes of these members, is integrally formed with a threaded adaptor portion 48 for threaded engagement with any suitable support. As will be understood, adaptor portion 48 may be of any other suitable form for desired mounting purposes, as for example an apertured cross-bar for bolting to a fixed support.

For the purpose of providing a conduit for wire leads 50, 51 connected to lamp sockets 8 (see FIGURE 1), housing boss 41 is provided with a tubular projection 52 (see FIGURE 2) which opens into the interior of housing 1, and connecting bar 45 is formed with a mating thermally insulating tubular projection 53 which telescopes over tubular silicone rubber coupling 52. The remaining portions of swivel members 43 and 44 to which tubular projection 53 is connected are hollow and form, in the support assembly shown in FIGURE 2, a continuous conduit through which the wire leads 50, 51 pass from the interior of housing 1 to the exterior, or to other hollow supporting members or conduits as desired.

Sighting means for aiding in the alignment of the floodlight beam are provided by the ends of the wire hinge 20 projecting from the sides of frame 3 in conjunction with raised portions 5a, 5b on the cooling fins 5 at each end of the unit (see FIGURES 2 and 3). Additionally, a channel-type sight 55 may be provided in the top central portion of door frame 3 for this purpose.

The invention thus provides a floodlight of compact and rugged construction which affords numerous advantages. The mounting of the cover glass spaced from the frame allows the glass to be readily washed off, such as by rain, while providing for draining of the water entirely away from the unit. The combined stop and fastening means described provides for accurate positioning of the door frame on the housing, for limited compression of the sealing gasket which prolongs its useful life, for good heat transfer between the frame and housing, and for retaining the fastening screws in loss-proof position and making them less subject to tampering. In addition, the hinge means described enables the door frame to be somewhat flexibly connected to the housing to facilitate alignment of the fastening screws in securing the door frame to the housing, it provides for the door frame to be swung completely away from the front opening and laid on top of the housing if desired, and it permits ready detachment of the entire cover for cleaning or change of the glass pane if desired. Furthermore, the socket mounting arrangement is such that the socket supports are completely within the housing and thus it avoids the leakage problems attendant on insertion of socket supports through openings in the housing walls, as characterized the prior devices.

It will be understood while the features of the invention have been described specifically with respect to a floodlight, they may find application to other types of devices.

While the present invention has been described with reference to particular embodiments thereof, it will be understood that numerous modifications may be made by those skilled in the art without actually departing from the scope of the invention. Therefore, the appended claims are intended to cover all such equivalent variations as come within the true spirit and scope of the invention.
